We've started working our way through parts of this book as a read-aloud for younger children but have enjoyed it especially for the pictures. It covers everything from the Hubble Space Telescope to the surface and atmosphere of the Sun, Moon and Planets, from Space Pioneers to star maps, from explanations of various types of telescopes to black holes and discussions of the possibility of extraterrestrial life. We've only read a small portion of the text so far, but were pleased to find that the text came out better than expected in several litmus-test areas. The detailed charts on things you can see in the night sky was very helpful.
